禁止使用 void 运算符,因为它不是一个熟悉的运算符。
¥Disallow the use of void operators, which is not a familiar operator.
void运算符通常仅用于获取未定义的原始值,通常使用void(0)(相当于void 0)。在这些情况下,可以使用全局变量undefined。¥The
voidoperator is often used merely to obtain the undefined primitive value, usually usingvoid(0)(which is equivalent tovoid 0). In these cases, the global variableundefinedcan be used.
